How Can I Overwrite Previous Output in an FTP Downloader for a Streamlined Progress Display?

Overwriting Previous Output in FTP Downloader

In the context of an FTP downloader, where progress updates are constantly being printed, it's often desirable to overwrite previous output with updated information instead of generating separate lines. This can provide a more streamlined and readable view of the download status.

One approach to achieve this is using the end keyword in the print function. By default, print appends a newline character to the end of the line, but specifying end='r' allows the cursor to return to the beginning of the current line.

Consider the following modified version of the given code:

print(os.path.getsize(file_name) / 1024 + 'KB / ' + size + 'KB downloaded!', end='\r')

Here, the end='r' argument effectively replaces the newline character with a carriage return. This keeps the cursor at the start of the current line, enabling the subsequent print statements to overwrite the previous line.

As a result, the output will continuously refresh, showing only the latest progress information without creating new lines. For example:

1784 KB / 1829 KB downloaded!
1788 KB / 1829 KB downloaded!
...

This technique can be particularly useful when creating user interfaces or displaying real-time updates where it's beneficial to minimize screen clutter and keep the focus on the relevant data.
